What does Pennant AI do?
Pennant AI builds an AI-native corporate governance operating system for institutional investors, public companies, and their advisors, starting with proxy voting and shareholder engagement. The platform analyzes SEC filings, shareholder proposals, and voting guidelines to generate policy-aligned recommendations while keeping humans in the loop. Founded by former BlackRock, State Street, and PJT Partners professionals, it is part of YC's Summer 2026 batch.
